Looking forward to the real thing.
This concept seems interesting, and you have a really good mastery of colors. As trailers go, the text passed just a bit too fast, and the music seemed to change a little awkwardly, but overall, it was very nice. I'm not sure whether you've finished it by now, since this movie was posted a long time ago, but I'm certainly looking forward to seeing it! (4/5, 9/10)
(my Japanese isn't very good, and Newgrounds doesn't let us use japanese text, but for your benefit, I'll try to translate my thoughts below)
